FANCY-ROLLER FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 635,927, dated October31, I899. Application filed December 3, 1898. Serial No. 698,160%. (N0modeL) fibers which enter between theteeth of the.

drum in passing the workers there was used a fly or fancy roller whichhad to bring the fibers t0 the point of the cards, so as to enable thedoffer to grasp the fibers. For this purpose the fly or fancy roller wasprovided with cards in the kind of a brush which by the great elasticityand the particular position of the teeth were enabled to catch in theteeth of the drum and to lift the fibers.

The fly or. fancy roller commonly consists in a wooden roller withseveral carding-sheets having long and elastic teeth set at. a certainangle, by which position of the teeth and the very rapid revolution ofthe roller the lifting of the fibers is attained. By the working of thisfly or fancy roller the flying out and about of the fibers cannot at allbe avoided in consequence of the great movement of air at thecircumference of the roller resulting from the rapid revolution of thelatter. The light fibers thus sucked and spread about deposit upon thefleece and are the cause of ununiformity. The present invention has forits object to overcome this deficiency.

Figure 1 shows the parts of a carding-en gine in section. Fig. 2 is anelevation of the parts shown in Fig. 1. Fig. 3 is a sectional view ofone of the rollers of the fly or fancy rollers.

The carding-teeth are set in an endless band of leather, cloth, or othersuitable material a, which is carried on by two rollers 19 c of thewhole width of the cardingengine. The

roller b, of larger diameter than roller 0, re-' ceives its movementfrom the drum d by means of a pulley 6, carried on the axis of theroller I), while roller 0, of smaller diame= ter, is rotated by thefriction of the endless band or the cards a upon its circumference andis adj ustably supported in bearings f for the purpose of regulating thetension of the endless band a. The latter moves in the direction of thearrow, and the carding-teeth travel in a straight line from the pointwhere they enter the drum to the point where they leave the drum cl. Forthe purpose of attaining a safe guide of the carding band upon itsrollers the latter are provided with recesses g g, and upon the endlessband a are riveted straps h, which enter the recesses. A casing t,surrounding the two rollers b 0, serves as protector for the cards ofthe fly or fancy roller. By this arrangement the carding-teeth of thefancy-roller do not leave the drum d in a circular line, as hitherto,but in a line which is directed tangential to the circumference of thedrum d. Moreover, in consequence of this arrangement a much greaternumber of carding-teeth are acting with the teeth of the drum d, bywhich the employment of a less number of revolutions of the fly orfancyroller is afforded, and a destructive air circulation by which thelight fibers could be blown about is avoided.

Having now described and ascertained my said invention and in whatmanner it is to be performed, I declare that what I claim is In acarding-engine, a fly or fancy roller comprising a pair of parallelrollers journaled in proximity to the main cylinder, an endlesscarding-sheet carried by said rollers and running with its surfacetangential to said main cylinder, and means for driving one of saidrollers, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
